To avoid malfunctions, have your Citroën specialist regularly check the full status of the charging circuit. Before winter, have your battery tested using a tester. You will have the option of a preventive change and avoid the inconvenience of a breakdown.
Avoid extreme temperatures that damage the active material, which reduces the conductivity of the electrolyte (a mixture of water and acid) and weakens and deteriorates the battery. Pay attention to the alternator too; if it is faulty, it can use up the battery prematurely.
